ive noticed that the oil sump pan on my doner 3.5L enigne is a litttle dented, some one may have used it as a jacking point.
will this effect the oil pickup at all?
if so can i use a 3.0L sump?

From memory the pickup is in the of them.. It would be around the lowest point of the sump which is going to be close to the Sump Plug. Best thing is pull it off. Take a look in the inside. If damage is only minor maybe you can tap it out..:) Not sure if sumps are the same. Take a good look at them..:)

Dented oil pans is (from what I have read) one of the major causes of spun bearings due to oil starvation, Id take it off, and bash it flat with a piece of 2x4" :D

so you are telling him to bash it out with a bit of timber??? :bowrofl:

a hammer or some form of blunt "metal" object would do the job better ;)

Id go the timber route, just use an offcut and a mallet or hammer and use it to tap it all flat

awsome thanks guys, if its bad, i could use the 3.0L sump if they are the same

Yeah they are the same

Timber is a better option.

Timber is softer than metal, so you wont damage the pan in the process. Timber also has a decent flat surface....

Dad used to beat out the panels on his XD falcon with a 2 x 4 and a large mallet - its amazing how flat you can get the metal with some timber :)

as far as i know they make a HUGE change to oil pressure and feed.
sr20 + dinted sump = siezure from what im told, apparently those motors are known for it

i can tell you from experinece the pick up point is some 7mm from the bottom of the sump on an SR20.

It doesnt take much of a hit to bend the alloy in this far, but even a 5mm indent will cause issues at higher rpms as the oil being viscous doesnt travel into the space as freely and eventaully you have a starvation problem

Same as DOHC 3L's - very common
Micjaiy....That's how you do it....just like Ers said.
My 3.5L DOHC sump had a massive gauge in it so bashed it out with a piece of timber but in the end decided to get another better condition one.

threadmine!

Ok so following my member machine thread my oil sump pan is stuffed. Anyway have got a new one blah blah but tonight I got under the car and untightened all the bolts etc for the pan not to fall off! Seems like the engine's previous owner/server has sealed it with a blue sealant. Is there anyway to get it off with the sealant there? Ive tried a scalple to no avail...

get a flat head screwdriver and a mallet. slowly, working your way around the sump, push the screwdriver between the block and sump making sure not to damage the block face.
the sealer does a damn good job of sealing up the sump, but it also acts as a damn good glue. so patience is a virtue. Once you're ready to put it back on, go get your self some 'Copper RTV' from Autobarn and put it on BOTH sides of the new sump gasket. that is, do the block, then do the sump, place the gasket on the sump, mate it to the block and screw it back in:)

AFAIK there is no sump gasket for the 3rd Gens, the blue sealant is what makes the seal.

EDIT: Voila...

Also Danny, If you dont want to buy it Im 99% sure I have a tube of it and IIRC it hasnt been opened.

Sweet cheers man. Why arent you out at the Belmore? lol Planning on doing this tomorrow so probably wont have time to grab it but I'll see how I go. Stupid car is stuck down at the unit...

Mate! Use a strong paint scraper. I tried using screwdrivers but it was too big and would ruin the oil pan, if you use a scraper it will slice the gasket goo very nicely, dont even need a mallet. Give that a go :D

Cheers tuffy will give that a try!!!

don't be afraid to give it a bit of a bit with a SOFT (RUBBER) HAMMER too can break the seal (or at least loosen it up a bit)

how much clearance is there between pickup and bottom of pan in the sohc 3.5l? i have a small dent on the front corner, drivers side due to brother having these huge rocks either side of his narrow, steep driveway, and while going down drifted to the side and one of the rocks went under the bottom suspension arm and hit the sump. was so damn lucky it didnt pierce it. sounds dumb, i know but his drive way is so steep, and narrow its hard to keep on the concrete.

Ended up getting a scraper like Tuffy suggested however it did require getting a corner into the sealant and giving it a good whack :)

Yeah, the hammer and lump of wood method works well. Most engines have minimal clearance between the pickup and metal of the sump, its always at the lowest point where the damage is likely to occur. While the sump is off check that the screen isn't clogged or that the dent in the sump hasn't moved or split the pickup tube itself.

There is a special tool that gets inserted into the sealant and then hammered along the joint line, but as suggested a paint scraper works well too.

just to add, new sump pans are cheap as. something like $30.

part number MD323012.

while you're at it, get a new plug and o-ring (MD321251/MD321252) for around $5.
